Got the scope mounted with one pieace scope mount and once focused and sighted my groupings have improved. I liked the Parallax AO adjustment because once you have a clear picture you don't have to guess the distance of your target. The scope is also light and has not affected balance to my Crosman G1 Extreme
Pros: Clear Optics and easy adjustment
